COMBINED PLOW AND sorn PU vEJaIzn i Application-filed August 8, 1927Serial No. 211,475.

My invention relatesito that class of plows and soil pulverizers inwhich there located at the rear end of the plow moldboard aseries ofsoil pulverizer. blades arranged to rapidly 8 rotate andstrike upon theribbon of soil as blades and the clod holder.

it passes from the moldboard with the effect of completing the turningof the. soil over into the furrow and pulverizing it.

, My object isto provide a device of simple, durable and inexpensiveconstruction that may beusediin the nature of an attachment for a plowand soil pulverizer ofthe class described, when the plow is to be usedin earth that. is not readily broken up and contains tightly packed,clods, or masses of soil or other material, for the purpose oftemporarily. and. 'yieldingly holding clods of soil or the like in thepath of therapidly rotating blades, to thereby cause such clods to bepulverized before dropping into the furrow and I Further it is my objectto provide a device of this character so constructedthat when a stone.or like substance, which cannot be broken up by the pulverizer blades,is momen '7 tarily held in the-path of the pulverizer blades,the-,pressure of the blades uponthe'.

stone .will cause the holding device toyi'eld,

I thereby permitting the stone to fall into the furrow without'injuryto-the-blades.

My invention consists in theconstruction,

,arrangement and combination of the various parts of the device, wherebythe objects contemplatedare attained, as hereinafter more .fully setforth, pointedout in my claims, and illustrated in the accompanyingdrawings, in

which:

Figural showsaside elevation of a com a rear end elevationof a portionof the plow and soil pulverizer and my improved clod holder appliedthereto. In this view there is shown at the land side of the plow asection of earth before being plowed, and on the furrow side. a. sectionof earth that has been plowed and pulverized, and between the plow shareand furrow there is illustrated a ribbon ofearth turned to an elevatedposition by,

the plow and being pulverized and thrown laterally in the furrow by thesoiljpulvers izer, andalso showing clods of earthtenipor arily. held bythe'clod holder in position to be repeatedly struck-by the pulverizingblades during their passage between the p-ulverizing F igured shows asimilar view, except that instead of the clods of earth there isillustrated a stone which cannotbe broken up by the pulverizing iblades, and which is shown in position forced laterally by the impact ofshow-n attached tothis frame The plows are of the 'ordinary constructionI and comprise a fplow share 11, a moldboa'rd 12 and a land side 13. Themoldboard differs fronrthemoldboards commonly used in plo ws'inthatitslength from front to rear is. onlyabout half the length of an ordinarymoldboard, and it of itself in some instances completes theturning' overofthe soil into the furrow. "Immediately in the rear, of the inoldboardjl'Z-is an upright shaft 14, upon wliichthere is mounted a seriestcfpulverizing blades 15, so arranged that when the sh aftis rotated, thesepulverizing blades will engage the ribjbon of soil as it passes from themoldboard,

and complete the turning of this ribbon of I soil over into the furrow,and at the same ,time pulverize thesoil a-nd throw it laterally anddownwardly into the furrow.

' In use with plowsand soil pulverizersjust described, the plow shareand moldboard cut,

from the earth a ribbon like layer of soil and turn it up on edge, andthen turn it substantially up side downinto the furrow, and in thisspecification where Ire fer to a. ribbon of soil I mean this quantityofsoil thatis being cutloose, turned on' edge and thrown 7 intothefurrow. I v r I 'lVith plowsand soil pulverizers of this character inactual use, I have observedthat, I at times the: soil contains clods oflarge size and sotightly packed or hard that when not be broken up andpulverized, but will be thrown laterally and downwardly into the struckby one of the pulverizer blades, it'will clamped thereto by a'olevis 17.Fixedtothe of round rods "18 made of spring materiah .These' rods areextended rearwardly and downwardly, as shown inFigure 1, and lat-f 2,with their cen- A furrow without being pulverized. This action alsosometimes occurs with tightly packed masses of soil and plant roots andthe like. r

a For" the purpose of breakingup verizing all such clods or massescomprising an upright frame member 16 designed to be placed adjacentto'a' part of the frame and to be detachably and adjustably lower end ofthe frame member 16 is aseries erally as shown. in Figure tral portionsspaced laterally from the moldboard 12 and the rear ends spacedlaterally"from the pulverizing blades 15, as shown in Figure 2. Thefrear endsof'these rods are free and unobstructedso they may nove laterally awayfrom the soil pulverizer, and" thathave heretofore been employed on ordinary lowsio'r the purpose of directing large or tall vegetationdownwardly. and into the' so'they will not become caught or entangled in.any of the material passing near or between them. These clodholdingrods are somewhat similar to the ordinary weed hooks furrow sothat the ribbon "of soil may be de posited on top extent erform the samefunction as theweed hooks,

tains hard clods or tightly packed masses of roots or soil, then as the,plow progresses a ribbon of soil will be turned up on edge and thentheblades will strike rapidly upon causing the soil to be pulverized thisribbon of soil while it is being held in an elevated position by theplow, thereby and thrown laterally and downwardly through the clodholding rods.

l have observed in practice that'when the clods are relatively hard, the'blades will not completely break them up and pulverize them on thefirst impact of the 1 blades upon the1n,and under such conditions theclod holdingrods will prevent these clods from moving laterally awayfrom the pulverizing' blades, but will hold said clods temporarily inthe path of the pulverizing blades,

so that a number of blows by thepulverizing blades is struck upon eachclod,.and whereby even the hardest clods of soilxor the most tightlycompacted masses of vegetation will 7 be thoroughlybroken up andpulverized, "caused to pass through the clod holding rods or fall intothe furrow at the rear of the clod holding rods. By having the rear endsof the clod holding rods inclinedslightly downand pulhave provided adevicein' the' nature ofan attachment engage the surface of the stone,

device supported .pulverizer blades and of them. However, in the newarrangement. and combination-of part-s J herein dlsclosed these rodsWlll to a certain ut'in addition to that they perform in combination'another'and very important function.

In practical use, and assuming that the de- Y vice is being operatedupon earth which con a of the pulverizer blades,

and

wardly as they pass the pulverizing blades,-

the clods are thereby moved downwardly as f well as rearwardly, so thatthe blades strike downwar ly and'rearwardl a i T WVhen a stone or othero struction which different arts of the'fclods as the clods move cannotbe broken up by the pulverizing blades asses between the pulverizingblades, and the there is no injurious effect upon clod holder, h thepulverizing blades, because when they they will force' it outwardly, andthis pressure upon yield laterally ting th'estone holding rods and dropinto the furrow. This and outwardly, thus permitaction is illustrated inFigure 4 of the draw- I being also shaped to prevent large clods of soilfrom moving laterally through it and to temporarily support such clodsin the path of the pulverizer blades.

In combination with low and a soil to pass to the rear of the clodthe stone will cause the clod'holding rods to 7 permit the" pulverizedsoil to be thrown V laterally through it,said clod holding devicepulverizer formed with bla esarrang'ed to strike upon the soil while itis in positionelevated by the plow, and thereby throw itlateiv ally awayfrom the plow, of a clodholding device supported in spaced relationtothe pulverizer blades and shaped to permit the soil elevated by theplow to pass through the ulverizer' blades space between itanid the; h Vand to permit the pulverize soil to be thrown I laterally through it,said clod holding device being also shaped to prevent 'largeclods ofsoil from moving laterally through it and to temporarily support suchclods in the path I said clod holder being yieldable laterally so thatstones'or the like too large to pass laterally through the clod holderand through the space between the clod holder and the pulverizing bladesmay be moved laterally by the pulverizing blades, and thereby force theclod holder 1 laterally far enough to permit the clods to pass betweenthe. clod holder and thefpulverizing blades.
